Abstract :
two digraphs of same order are said to be skew- equienergetic if their skew energies are equal. one of the open problems proposed by li and lian was to construct non-cospectral skew-equienergetic digraphs on n vertices. recently this problem was solved by ramane et al. in this paper, we give some new methods to construct new skew-equienergetic digraphs.
